I’ve been doing more videos on platforms like TikTok. I like the auto subtitling and some of the formatting that’s common on TikTok. However I don’t love the creator tools like TikTok Studio or Capcut. I’m increasingly trying to record in OBS Studio and subtitle locally. This automates that piece. Nothing super complicated but made a common task for me much easier.
Using it
If you have ffmpeg, python3, and python3-venv installed, this script should work as is. I’ve only tested on linux but this should work on Windows or macOS as well. I’ve got it available in a GitHub repository.
Auto translation
I have also been posting to RedNote where it’s common to use Capcut to auto subtitle in English and auto-translate to create Mandarin subtitles. I have a hacky version of this script that offloads the translation part to a server I have at home with a GPU. The translation models should work on a CPU without being unbearably slow so I’m hoping to add that as a feature here too.
